I test drove the IS-F a while ago and that thing is a beast, if only lexus didn't style it so ugly. If anyone of you have seen the five-axis is-f, that is what lexus should have done! The transmission is surprisingly good and atleast it doesn't have a gas guzzler tax. Handling is not bad at all and better than most vehicles out there, but its not M3 good. If I was in the market for a 4 door, I think I would choose the is-f over the e90 m3. Lexus did a great job on their first try.
